Definitions

  • the present invention relates to an agricultural application machine for discharging granular material, in particular seed and / or fertilizer grains, with conveyor lines for conveying the Guts to Ausbringierin by means of which the good on / in the ground can be stored, wherein at least one conveyor line with an acoustic detection device is associated with at least one microphone for acoustic detection of Gut barngangs by the delivery line.
  • the US 4,057,709 discloses a dispensing machine according to the preamble of claim 1.
  • the present invention is therefore an object of the invention to provide an improved agricultural dispensing machine of the type mentioned, which avoids the disadvantages of the prior art and the latter develops in an advantageous manner.
  • a contamination-resistant, permanently accurate grain detection is to be achieved, in which the acoustic detection device is designed to be easy to install and preferably also retrofittable.
  • the microphone - or possibly Also several microphones - are attached to different points of the delivery line.
  • the normal, inherent course of the delivery line, for example, from the distributor head to Ausbringelement need not be changed for this purpose.
  • the delivery line can be passed on the microphone with the same wall thickness and constant material as on the other line sections.
  • the delivery line can remain unchanged in terms of wall thickness, line cross section, line material and wall contouring and correspond to the corresponding average values of the delivery line at other sections.
  • the delivery line may in this case be formed as a plastic tube, preferably hard plastic tube or metal tube, whereby mixed forms may be used, for example in the form of a plastic-coated metal core tube.
  • Said coupling element in this case surrounds the delivery line on the outside thereof at least partially, wherein the coupling element designed as a damper in particular can sit flat on the delivery line and be connected to it in a planar manner, in order to attenuate line vibrations directly in the microphone environment.
  • said coupling element can form a sleeve-like damper sleeve, which sits on the delivery line or through which the delivery line is guided, wherein said damper sleeve firmly surround the delivery line outer side or can thus engage in a form-fitting or flat manner.
  • Said damper sleeve can in this case be designed to be closed in an annular manner or, alternatively, also be designed to be open peripherally in the manner of a slotted sleeve.
  • the damper sleeve and thus the microphone, if necessary, also postponed later on an already mounted conveyor line be, in particular at yielding and / or elastic design of the coupling element.
  • the coupling element may also be formed in several pieces in order to enable such a transverse placement of the coupling element on the conveying line. As a result, the retrofitting of the acoustic detection device is facilitated on existing dispensing machines.
  • this damper sleeve may have a peripheral receiving recess for receiving the at least one microphone, which receiving recess may be formed open to the sleeve interior and / or the delivery line to unimpaired impact noise of the grains to the conveyor line wall to transfer the microphone.
  • Said sound and vibration damping coupling element may comprise a solid muffler body of sound-absorbing material in a further development of the invention, which is suitably vibration and sound-absorbing and usually have a relatively large specific gravity and can be sound-absorbing.
  • the massive muffler body may consist of bitumen.
  • the microphone may be mounted in the region of an arcuately curved line section, preferably on the outside of this curve arcuate line section, so that in this arcuate line section, so to speak out of the curve carried line grains directly on the line wall hit the outside of the curve, with the microphone lying directly above this line wall on the outer side of the curve.
  • Said arcuately curved line section may be a line curve provided in the normal line course and does not need to be provided specifically for the acoustic grain detection.
  • a curved curved line section also special be provided, for example, by a hose bend guide to position the microphone at a specially desired line location can.
  • an evaluation device connected to the microphone may comprise a filter element for filtering out of the microphone signal.
  • a filter element for filtering out of the microphone signal.
  • such interference can be filtered out by such a filter element, which can not be damped away by the damper element described above and / or can not be generated by the flow of material, which is conveyed under predetermined operating conditions through the delivery line.
  • This can be achieved by experiments in model operation, for example in a sound-damped test room in which the seed or fertilizer grains are left in a similar manner through the delivery line and the noises occurring in the process are examined.
  • a good-current-conditioned noise spectrum can be detected and stored so that noise occurring in the actual field operation outside of this good-current-specific noise spectrum can then be filtered out.
  • said filter element may comprise a bandpass filter for filtering out predetermined frequency ranges.
  • the named evaluation device which evaluates the microphone signals, can in principle execute different evaluation functions or have different evaluation modules.
  • the evaluation device can provide a grain count and / or a determination of the longitudinal distribution of the grains, that is to say the speed-dependent spacing or the grain spacing per unit time, in particular in the case of single-grain sowing or isolated grain conveying.
  • the evaluation device may also include a blockage detector for detecting a blockage in the respective delivery line and / or for detecting a blockage of the distribution head exit.
  • a separating device can be provided between the distributor head 8 and the dispensing elements 10, which can be provided on or in front of the dispensing elements 10 or at or shortly after the distributor head 8.
  • microphones 12 are associated with an acoustic detection device 40, whereby the microphones 12 can in principle be provided at different sections of the conveying lines 11, for example closer to the dispensing elements 10 or closer to the distributor head 8, in particular also downstream of the separating device.
  • the microphones 12 assigned to the delivery lines 11 one or more microphones 12 can also be assigned to the delivery line 5 upstream of the distributor head in order to generally monitor the flow of material there.
  • Fig. 3 shows the microphone 12 is mounted by means of a noise and vibration damping coupling element 13 on the conveyor line 11, said coupling element 13 may form a solid, possibly slotted damper sleeve, which can sit flat on the outer surface of the conveyor line 11.
  • the said conveyor line 11 extends here without special measures on its wall, in particular with a constant cross-section and constant wall thickness through the coupling element 13 and thus past the microphone 12.
  • the sleeve-shaped coupling element 13 has for receiving the microphone 12 circumferentially a receiving recess 14, which may be formed, for example, as a radial, inwardly open bore, so that in the area Receiving recess 14, the wall of the conveying line 11 is open and directly facing the microphone 12 without the interposition of damping coupling element material.
  • Said evaluation device 15 is provided to evaluate the microphone signal in the desired manner.
  • Said evaluation device 15 may in this case have a filter element 16 for filtering out interference-current interference signals from the microphone signal in order to increase the evaluation accuracy.
  • Said filter element 16 may in particular comprise a bandpass filter for filtering out predetermined frequency ranges.
  • Said evaluation device 15 can have various components for determining various application parameters, for example a grain counter, a longitudinal distribution determiner, a clogging detector or a flow rate determiner, wherein said components can advantageously be designed in the form of software components.
